LAMP-SHADE.

To allwhomz'tmay concern: 2

Be it known that I, Isaac B. BEALES, a citizen of the United States, anda resident of Hasbrouck Heights, in the county of Bergen and State ofNew Jersey, have invented a new and Improved Lamp-Shade, of which thefollowing isa full, clear, and exact description.

Among the principal objects which the present invention has in view are:to permit the shipment of shades of the character mentioned in compactform; to provide means for readily assembling the separable parts of theshade; to provide means for connecting the separable elements in closerelation to avoid rattling, and to simplify and reduce the cost ofconstruction.

Drawings.

Description.

As seen in the drawings, the shade is made up of a series of panels. Thepanels are separably united and are held associated as in service bymeans of a rigid wire frame 12. The frame 12 has a series of radials 13and a central supporting ring 14. For engaging the frame 12, the panelshave each an extension 15, which as shown in the draw ings, is foldedover the laterals of the frame 12. The panels have a central translucentSpecification of Letters Fatent. I P tgnted M31, 30, Application filedJune 13, 1918. Serial No. 239,799.

and preferably decorated center 16. The center 16 may be constructedfrom parchment or glass as preferred, also the center may be homogeneousor formed of parts united and arranged in artistic fashioning as inthe'so-called leaded-glass constructions. The centers are held in metalframes 17 and in channels formed by groove members 18 at the inner sideof the panels. Any

suitable form of assembling the centers 16 and the frames 17 may beemployed.

While I prefer to construct the groove member 18 as a homogeneouselement, it will be understood that the lower extension 19fof the saidmember may be parted at the ends thereof from the side extensions of thegrooved members to permit the introduction of the center 16 into thegroovesformed by the lateral extensions to be there held by turning upthe extension 19 to thereafter hold the center. 16 in service relationto the frame and to the completed shade. panels of the shade whenprovided with their respective centers are united for assemblage to formthe completed shade by means of the slip oints shown in Figs. 4: to

7, inclusive.

As aboveindicated, when assemblage has been effected, the panels areheld 1n servlce relation by turning the extensions 15 with which thepanels are provided over the laterals of the frame 12. The shade isplaced in service by means usually employed for 1 installing articles ofa similar character, to

wit, the weight of the shade is carried on the ring 14: of the frame 12.

When it is desired to ship the shade, it is separated into its elementsby disengaging the extensions 15 with the laterals of the frame 12, andslipping the panels out of engagement with each other. It will beobserved that when the panels are so disengaged from each other and fromthe frame 12, they may be packed together with the said frame 12 to forma small package and one in which the elements may be easily protectedfrom breakage during transportation. At the same time, it is obviousthat the package having arrived at its destination, a novice with verylittle instruction may reassemble the elements to form the shade forservice.

In Fig. 4:, the most simplified form of slip joint employed forconnecting the panels is shown. Each panel is provided with lateralextensions bent to form outwardlyopening channel members 20 andinwardlya back of the frame 18 to the free edge of the flange formingthe channel 21 and to the back of the channel member 20 when the flangethereof is held in the channel formed by the inwardly-opening channelmember 21.. It is obvious from this arrangement of the parts that themembers 20 and 21 can only be separated by sliding the same endwise ofthe laterals of the frame, and that when this is prevented by thesupports afforded by the extensions 15, the panels are heldapproximately rigid in service relation. In Fig. 5 of the drawings, aslip joint is shown as having at one side of the panel an open tubularchannel edge 22. At the opposite side of the panel, a rolled rib-likemem ber 23. is formed ofiset from the face of the frame of the panel toenter and fill the interior of the channel edge 22. This form of slipjoint is preferred when constructing the shades in forms such as shownin Fig. 3, the spheroidal shape being better accommodated by the jointshown. I V

A similar joint is formed in Fig. 6 adapted for use on a rectangularform of shade.

In Fig. 7, a further modified form of slip joint is shown, whereincorner members or fillets 24 are formed. These members are shaped incross section to any desired form the fillet are juxtaposed to thecenter edges of the frame, thereby securing a tight joint for theconstruction.

WVhile the method of assembling the elements constituting the lamp shadehas been described as requiring that the extension 15 of each panel beoverturned on the laterals of the frame,in some instances andparticularly where the frame is more rigid, I prefer to turn theextensions 15 when constructing the panels, and to assemble the panelsbefore disposing the frame having the laterals 12 in position, the saidlaterals then dropping into the channels formed by the overturnedextensions 15.
